1756-1820. Welsh Calvinistic Methodist* theologian. He was born at Penucha, Flintshire, of a fairly well-to-do family. His only education was at schools in Caerwys and Holywell, but it gave him excellent grounding in the classics. He began to preach among the Calvinistic Methodists in 1783 and ministered to their societies at Mold, Ruthin, and finally Denbigh (1806-20). He was closely associated with [[Thomas Charles]] after whose death in 1814 Jones was the most learned and distinguished leader of the Calvinistic Methodists.
